Non-metallic safety filling container
摘要:
A non-metallic safety filling container is formed as a hollow wall having a continuously closed inner surface, terminating at openings for venting, pouring and filling. A trigger mechanism mounted to the container simultaneously vents the container and slides a ported cylinder into position to complete a pouring path from the interior of the container through the pour spout.
